Monoclonal antibodies against Proprotein Convertase Subtilisin/Kexin type 9 inhibitors (mAb PCSK9i) could be administered to lower LDL cholesterol in patients with muscle-related adverse events, but intolerance to mAb PCSK9i has also been described [[2]]. In Familial Hypercholesterolemia (FH), statins treatment is the first choice to lower LDL cholesterol and to reduce cardiovascular morbidity and mortality, however, up to 10% of patients treated with statins report intolerance [[1]]. We enrolled 5 patients in chronic LA (mean age 64 ± 8 years, female 60%) affected by heterozygous FH and AtheroSclerotic CardioVascular Disease (ASCVD), with history of statin intolerance and mAb PCSK9i adverse events (flue like syndrome in 3/5 patients, severe CPK increase in 1/5 patient and low therapeutic compliance in 1/5 patient).
